The terminology used herein in the specification of the present invention is for the purpose of describing specific embodiments and is not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0025] In order to make the contents of the present invention more clearly understood, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention.

[0026] Please refer to the attached Figure 1-6 A new type of LED patch lamp includes lamp beads and a driver. The lamp beads are connected to the driver. The driver is provided with a DIN interface and a DO interface. The DIN interface and DO interface of adjacent patch lamps are connected. A serial decoding module and a shaping forwarding module are provided between the DIN interface and the DO interface in the driver. A control module is provided in the driver to cooperate with the serial decoding module, and also includes a constant current drive output module and a voltage stabilizing module.

[0027] The constant current drive output module includes R pin, G pin, and B pin;

[0028] R pin: Red N tube open drain, constant current output;

[0029] G pin: Green N tube open drain, constant current output;

[0030] B pin: Blue N tube open drain, constant current output;

[0031] The lamp power includes 0.2W and 0.5W, and the driver input voltage is 7.4V

[0032] The driver includes a PCB circuit board and an electrical component assembly connected to the PCB circuit board. The size of the PCB circuit board is 20mm-12mm-0.8mm. The control module includes an FW1903 chip connected to the PCB circuit board. Other chips that match the lamp beads can also be used.

[0033] In a specific implementation of the present invention, the chip cascade and data transmission and forwarding process is as follows: the controller sends data (D1). When chip 1 receives the first 24 bits, it has not yet forwarded data (D2). Then the controller continues to send data, and chip 1 receives the second 24 bits. Since chip 1 already stores the first 24 bits, chip 1 forwards the second 24 bits through DO. Chip 2 receives the data forwarded by chip 1 (D2). At this time, chip 2 has not yet forwarded data (D3). The controller continues to send data, and chip 1 forwards the third 24 bits it receives to chip 2. Since chip 2 also already stores a 24-bit, chip 2 forwards the third 24 bits (D3). Chip 3 receives the third 24 bits. At this time, if the controller sends a RESET low-level signal, all chips will reset and decode the 24-bit data they received and control the RGB port output, completing a data refresh cycle. The chips then return to the receiving ready state.

[0034] It can be used by combining two batteries to output 7.4V voltage. In order to ensure that it meets the needs of lamp beads, such as Figure 4 As shown, the voltage is reduced by matching R1...R4.
